THURSDAY, March 19, 2015 (HealthDay News) -- Children conceived through assisted reproductive technology, such as in vitro fertilization, are twice as likely to have autism as those conceived without assistance, a new study finds. But researchers only found an association, which may be explained by multiple births and other risks, not the infertility treatment itself, experts said.

The study included nearly 6 million children born from 1997 to 2007. After taking into account factors such as mother's education and multiple births, the increased risk was seen only for mothers under 35, the researchers said.
